    A particle executes SHM with a period of \[8\text{ }s\]and amplitude \[4\text{ }cm\]. Its maximum speed in cm/s, is

    A)  \[\pi \]              

    B)  \[\frac{\pi }{2}\]

    C)  \[\frac{\pi }{3}\]

    D)  \[\frac{\pi }{4}\]

    Correct Answer: A

    Solution :

    For a particle executing SHM \[{{v}_{\max }}=A\,\omega \] \[=4\times \frac{2\pi }{T}=4\times \frac{2\pi }{8}\] \[=\pi \,cm/s\]
